Patented June 1, 1909;

To all whom it may concern:

Be it known that I, FRED W GNER, of FairpIort, in the county of Monroe and State of ew York,- have invented certain new and useful Improvements in Can Bodies and Blanks Therefor; and I do hereby declare the following to be a full, ,clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon. l

The present invention relates to can bodies and blanks therefor of the type in which the heads have a rolled seam connection with the bodiesand it has for an object to provide a construction whose body is so formed that leaks at the juncture of the body seam and the heads are practically obyiated.

To this and other ends the invention consists in certain improvements and-combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the.

specification. 1

Inthe drawings: Figure 1 illustrates the two end portions of a blank constructed in accordance with this invention; Fig. 2 shows the blank with the seam forming flanges bent to be interlocked; Fig. 3 illustrates one end of a can body with the flanges interlocked; Fig. 4 lllustrates an enlarged plan of aortion of the body after the head engaging fl ange has been formed; Fig. 5 represents a horizontal SGCtlOIlOf the can body; and Fig. 6 represents an elevation of the can body with one head secured thereto, a ortion being shown in sect1on to illustrate it e rolled seam. Similar reference numerals in the several figures indicate similar parts.

Heretofore in the use of sheet metal cans with heads connected to the bodies by rolled seams a great deal of loss has been sustained by reason of leaks at the 'uncture of the body of the goo s therein. In this invention practically all leaks are obviated by reducing the meta at the 'uncture of the body seam and the heads. elongated sheet metal blank 1 or this purpose I rovide an w hich when rolled will make a cylindrical body. One end edge of the blank is provided with two V- shaped notches 2 which are arranged near the ends of the edge, while the other end edge, is formed with a flange 3 of a length substantially equal to the distance between the notches 2, chamfers 4 being formed'on those portions of the edge beyond the flange 3.

The flange 3 is doubled on the body to provide an inwardly turned flange which is interlocked with an outwardly turned flange 5 formed by doubling outwardly the edge of the body between the notches, thus providing the lips 6. When the flanges are interlocked the lips are overlap ed by the chamfered portions and each 0 the latter at its outer end is nearly coincident with the outer end of the roximate lip 6, as shown in Fig. 3, so that w....en the body is bent to form annular flanges 7 at its ends for engagement by the heads 8 a reduced amount of-metal will be present in the flange at the end of the body seam, thus permittin the heads 8 to be interlocked with the anges in the manner shown at 9, Fig. 6, without causing excesses of metal at the ends of the body seam.

@ans constructedin accordance with this invention may be manufactured with less exense, as there is less waste, and they will be ess expensive to canners because the destruction to their goods from leaks will be practically obviated.

I claim as my invention:

1. "A can body blank having one edge provided with two notches, one near each end flange having a length ap )roxiinately equal to t 1e distance between t e notches on the other edge, and achamfer arranged beyond each end of the flange.

' 2. Acan body formed from a single blank and having an outwardly" turned flange at one end of the blank, an inwardly turned EGBERT L. Ho LsKrN, A. E. HAZEN.
